My two friends and I were hanging out in my friend's bedroom. She has a rotating party light bulb and we were jamming out to music when my friend decided to take a photo using SnapChat on her iphone 5. It wasn't until later that we noticed the weird shadow blob that is between me and my friend. It cuts off the writing on her hoodie, but still shows my hand which creeps me out since we weren't even that for away from each other. I posted this here hoping to get some answers as to what this could be?
